NVR504-16 / 32B-P16-IQ

Name: Uniview NVR504-16 / 32B-P16-IQ
Brand: Uniview

16 / 32-channel network video recorder — 16 built-in PoE ports (30 W/port, 150 W total), four SATA bays with RAID 1/5, Ultra 265 compression, records cameras up to 16MP, with onboard Smart by NVR Face/Vehicle Detection and AcuSearch/AcuTrack AI search.

CHOOSE YOUR SIZE — TWO MODELS ON THIS PAGE

Rule of thumb: count your cameras across the whole site, then leave room to grow — 16 channels covers most single buildings; step up to the 32B-P16-IQ if you're combining several buildings or expect to add cameras later (note: both models have exactly 16 built-in PoE ports, not one per channel). Highlighted rows in the spec table below show every difference between the two.

Is this the right recorder for you?

Plain-language guide for buyers and installers — based only on what this recorder actually does.

Cameras plug in and power up — no switch needed16 built-in PoE ports (30 W per port, 150 W total budget, IEEE 802.3at/af) power and connect cameras with a single cable — most 16-camera installs need no separate PoE switch.

Storage that can't afford to failFour SATA bays with RAID 1/5 mirror or parity-protect the footage — a single disk failure doesn't wipe out your recordings.

Large sites & multi-building campuses16 or 32 channels in one box covers a full warehouse, factory floor, or multi-story retail location without stacking multiple recorders.

Growing camera countsBuy channels you don't use yet: the 32B-P16-IQ lets you add cameras later without replacing the recorder (only the first 16 channels get built-in PoE — see the notes below).

Wired alarm integration16 alarm inputs and 4 alarm outputs on the rear panel wire directly to sirens, door sensors or access-control triggers — no extra alarm hub needed.

Local-language interface38 GUI languages including Spanish (Latin America), Portuguese (Brazil) and French — your customer operates it in their own language.

Retail with POS & IP speakerPOS transaction overlay on all channels plus 16-ch IP speaker input make this recorder a fit for shops and cash-register aisles, not just back-office monitoring.

Quick incident lookup across many channelsOnboard Smart by NVR Face Detection, Face Comparison, SIP and UMD feed AcuSearch, AcuTrack, Face Snapshot Search and Vehicle search (up to 5 vehicle picture libraries, 25,000 pictures) — jump straight to the clip instead of scrubbing hours of 16- or 32-channel footage.

Not the right pick if you need…

Powering all 32 cameras via built-in PoE on the 32B-P16-IQ — this series has 16 PoE ports regardless of model; channels 17–32 on the 32-ch unit need a separate switch or injector
A second/redundant network uplink — only one 10/100/1000M RJ45 network interface is provided (separate from the 16 PoE camera ports)
RS232 serial connection — RS232 is listed N/A on this series (RS485 is provided, e.g. for PTZ control)
A fifth hard disk or more — this series tops out at 4 SATA bays (up to 96 TB total with four 24 TB drives)
Redundant/dual power input — it runs on a single AC 100–240 V power supply, no built-in PSU redundancy
